Mail on my Mac???????

I was trying to set up my yahoo account to be readable from my Mac mail on the desktop. It keeps telling me I need "mail plus" from yahoo. Are they serious? I need to pay them $20 a year to get my mail on the desktop?

Is there something I am missing?

Also, I purchased an email marketing program and I can't seem to access the yahoo server through that either. Is this the same problem?

If these are the cases, why can I access this and other accounts on my phone, but no where else?
